Upgrade Dependencies

[datasage]

This project is blocking another project I was upgrading. Since the dependencies have all been linked to a new major version(s) this should be considered a breaking change.

The following things have been changed in this pull request:

• PHP 7.3 is now the minimum version. This is also the minimum version of all current dependencies
• PHP 8.0 was not able to be tested just yet, mongodb extension does not yet compile with 8.
• PHP Code Sniffer was added to validate PSR12
• Psalm was added to handle static analysis. Some of the issues were fixed, the rest were added to baseline
• CI Workflow is now running on github actions
• The following packages were updated:
  • All ZF framework packages were updated to the laminas equivalents
  • Doctrine module packages were updated to the laminas version
  • Doctrine ODM is now linked to 2.x
  • PHPunit is now upgraded to 9.3

All tests except for one are now passing, the one that is failing is attempting to mock a now final class from Doctrine ODM. I am not sure this test is still needed. Some comments would be appreciated.

Hello @datasage

We are no longer using Apigility at PHPro anymore. Therefor, it is hard for me to make the correct decisions for this package.

We are looking for someone who wants to take over the package and can push it in the correct direction again.

@veewee I realized that after I did the work on this. I updated this for a downstream project. Now I am considering reusing the parts that that project depends on directly in that project.
